Description

Wall Switch Plate with Indicator Lights

technical field

The utility model relates to a circuit switch board, in particular to a wall type switch board with an indicator light.

Background technique

A fluorescent strip is arranged on the top of the pressing plate of the existing wall switch plate to display its position. Its shortcomings are: 1. The display is not obvious at night; 2. Fluorescence has negative effects on the human body and the environment.

Contents of the invention

The technical problem to be solved by the utility model is to provide a wall switch panel with an indicator light.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is: a wall switch panel with an indicator light, a transparent window is arranged on the upper part of the pressing plate located in the middle of the panel, and a light-emitting diode is installed on the switch behind it; The switch integrated with the panel is connected in series with electric loads such as light bulbs controlled by it on the circuit, and the resistor and light-emitting diode with larger resistance value are connected in parallel with the switch. When the switch is disconnected, the resistance value greater than the resistance of the electric load such as light bulbs, light-emitting diodes and electric loads such as light bulbs form a circuit, the electric loads such as light bulbs do not light up or do not operate, and the light-emitting diodes with extremely small power consumption light up. When the switch is closed, the switch and the electric load such as the light bulb form a loop, the light-emitting diode connected in parallel with the switch does not light up, and the electric load such as the light bulb lights up or runs.

The beneficial effects of the utility model are:

1. When the circuit is turned off, the light-emitting diode with extremely small power consumption lights up, and when the circuit is turned on, the light-emitting diode goes out. LEDs that light up at night clearly show the position of the switch.

2. There is no negative effect on the human body and the environment caused by traditional fluorescent wall switch panels.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Embodiment shown in Fig. 1-2: a kind of wall-type switch board with indicator lamp, comprises panel (1), press plate (4) that is positioned at the middle part of panel and the switch (5) that is connected with panel as a whole; The fluorescent strip on the press plate (4) top of the wall switch plate of the wall type is changed into transparent window (2), and light-emitting diode (3) is housed on the switch (5) of its back.

Circuit diagram of the present utility model as shown in Figure 3: switch (5) is connected in series with the electric bulb (7) controlled by it on the circuit, and resistance value (6) and light-emitting diode (3) and switch (5) of resistance value are 500 thousand ohms )in parallel.

When the switch (5) was disconnected, the resistor (6), the light emitting diode (3) and the electric bulb (7) formed a loop, the electric bulb (7) was not lit, and the extremely small light emitting diode was lit. When the switch (5) was closed, the switch (5) and the electric bulb (7) formed a loop, and the light-emitting diode (3) connected in parallel with the switch was connected in series with the larger resistor (6) of the resistance value, so it was not lit, and the electric bulb (7) ) lights up.
